Can'；t链接BLAS库与Clion 2016.1.2和Fedora 22，获得未定义的参考

我今天一整天都在为这个问题苦苦挣扎。我相信我在CMake上遗漏了一些小东西，因为这是我第一次使用它，我有所有这些错误

我的问题是，无论我如何更改或在Cmake文件中包含什么，我都会不断收到此错误

[ 25%] Linking CXX executable Matrix_Benchmark
CMakeFiles/Matrix_Benchmark.dir/main.cpp.o: In function `run_benchmark(double*, double*, double*, int, int, int, int)':
/home/lumx/git_projects/memory-traces/src/Matrix_Benchmark/main.cpp:202: undefined reference to `cblas_dgemm'
collect2: error: ld returned 1 exit status

我相信Blas和OpenBlas有问题，因为Blas或Blas-devel包没有cblas.h，我必须安装OpenBlas和开发库

到目前为止，我尝试了很多东西，我将包括一个凌乱的Cmake文件。对此我很抱歉，但我希望有人会发现更多错误，并帮助我改进这些错误

我还有这个include指令，用于cblas.h处理C和C++

#ifdef __cplusplus
extern "C"
{
#endif
    #include <openblas/cblas.h>
#ifdef __cplusplus
}
#endif

\ifdef\uuucplusplus
外部“C”
{
#恩迪夫
#包括
#ifdef_uucplusplus
}
#恩迪夫

好，修复了它

我不想在CMake文件中包含OpenBlas lib，出于某些原因，我不得不删除所有Blas、OpenBlas、Lapack软件包并重新安装。出于某种原因，我不得不重新启动系统使其正常工作。这是strage，但谁知道发生了什么

现在，CMake文件看起来像
